That question has many answers.

The logic 7 amp has 7 channels I think.

There are 2 amps out there that are better than the Harmon-Kardon amp.

JBL MS-8

And

Rockford Fosgate 360.3

But you need to keep the head unit and re-locate it in the rear portion of your car in order for an after mkt amp to work, if you have the logic 7 amp.

It's the hifi amp I'm guessing it's 6

If you are thinking of modifying or substituting after market amps .

It can be done fairly easily with the stereo and hi fi system
but not the L7 as described in the above documents.

ms-8 is no longer made
rockford 360.3 is a dsp not and amp.
stereo system head unit power 4 channels
Hi fi 6 channels amp is weak
Logic 7 9 channels connected to the idrive or radio
by fiber optics not easy or inexpensive to modify.

current popular modification helix 82dsp from bimmertech
and a set of aftermarket speakers for the fronts if you
have stereo or Hi Fi.
